Never one to shy away from uploading works-in-progress, Joel Zimmerman, aka deadmau5, shared a new version of his hip hop production featuring British rapper Shotty Horroh (pictured left) that features the mau5 himself playing the new bassline on an actual guitar.

The original surfaced in September of 2013 and surprised fans used to his progressive house stylings. Seemingly out of nowhere, we get an alternate version via his SoundCloud account (stream above).

This will likely be lost among the countless other spontaneous uploads and never be heard in its alternate form again, but check back–you never really know.
